Y=ax+b
a... slope
b... interception on the line y
you get the equation y=-1/2 *x + 12
Answer:
It's A
Step-by-step explanation:
It's just moving the equation to the right 4 units. There's no stretch, compression, or reflection.
Answer:a
Step-by-step explanation:The temperature rose by 80 so up the number line and dropped 20 so down the number line to 60
Answer:
The width which gives the greatest area is 7.5 yd
Step-by-step explanation:
This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen
